The iSlsk application is in early beta mode, and its developer isstill working out a few kinks. We encountered an error message others have mentioned that reads: "Your FireWire GUID could not be recognized and therefore music importing will not be available." Castro has acknowledged the problem, and recommends following these steps to get around it. However, that workaround did not work, and in fact ended up barring us from FTP on the iPhone (error message: "host is down"). Again, this is early beta software — install at your own risk — but successive versions should offer increased stability.

Castro apparently cobbled the program together from variousopen source Soulseek clients and a web-based client for the network that he put together previously. Castro (aka errrick), demonstrates iSlsk in the video to the right, and we’ve confirmed that the app works as depicted.

Castro says he started development in February, primarily to enable himself to download from Soulseek on his iPhone.

"I saw all thecapabilities this little gadget had and then thought, ‘Why didn’tsomeone already do something like this? I sawnew applications being added every day so I thought, ‘Hey, makingapplications for the iPhone shouldn’t be that hard’…. [I] thought howuseful it would be to have a P2P client (first for me, then for thepeople) so I started learning and developing it myself."
